Explanation:
Detailed explanation-1: -The primary physiologic responses to cold exposure are brown adipose tissue (BAT) thermogenesis and skeletal muscle shivering, which generate heat, and the constriction of blood vessels (vasoconstriction), which prevents heat loss.
Detailed explanation-2: -It maintains homeostasis, a stable equilibrium, of the skin and regulates body temperature. When our core temperature gets high enough through physical activity or high temperatures, sweating kicks off and cools you down while it evaporates. This can prevent dangerous conditions like overheating and heatstroke.
